This project is a part of a research effort by the T*AFSM in collaboration with US Army Natick Soldier Center. In this project we carry out numerical simulation of the aerodynamic response of a G-11 cargo parachute with retracted suspension lines. We investigate how these retractions influence the payload descent velocity and other aerodynamic performance characteristics. In our computations we use a combination of fluid-structure interaction (FSI) and 6 degree-of-freedom (6DOF) models.
